Hey there!
1. Arc IJ = 62
1/2(360 - 2(78 + 40)) = 62
2. Arc WY = 103
50 + 53 = 103
3. Arc DEG = 204
70 + 77 + 57 = 204
4. Use pythagorean theorem
12.4^2 = x^2 + 11.5^2
x = 12.3
5. Use pythagorean theorem
x^2 = 5.2^2 + 8.4^2
x = 9.9
6. Use pythagorean theorem
18.1^2 = 10.1^2 + x^2
x = 15.1
7. Use the formula for the area of a circle
A = pi x (10^2)
A = 100pi
A = 314.2yd^2
8. Use the formula for the area of a circle
A = pi x (5.4^2)
A = 29.16pi
A = 91.6m^2
9. Use the formula for the circumference of a circle
C = 2 x pi x 4
C = 8pi
C = 25.1ft
10. Use the formula for the circumference of a circle
C = 2 x pi x 3
C = 6pi
C = 18.9yd
11. Use the standard equation of a circle
4 = (x - 15)^2 + (y - 8)^2
12. Use the standard equation of a circle
122 = (x + 1)^2 + (y - 3)^2
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
I believe Jim is 44 and Jill is 35. 9 years apart. In 7 years Jim will be 51 and Jill 42. The sum of 51 and 42 is 93.
Answer:
0.8418
Step-by-step explanation:
We have p = 0.36
Sample size = 200
We have to find the standard error of proportion
= √p(1-p)/n
= √0.36(1-0.36)/200
= 0.034
P(0.30<p^0.40)
= 0.30-0.36/0.034 = -1.76,
0.40-0.36/0.034 = 1.18
P(-1.76<z<1.18)
When we go to the standard normal distribution table
P(z<1.18) = 0.8810
P(z<-1.76) = 0.0392
0.8810 - 0.0392
= 0.8418
This is the probability of the sample proportion being between 0.30 and 0.40
answer is 9
Change the sign of the exponent by rewriting the base as its reciprocal
3^2
raise 3 to the power of 2
you get 9
Answer:
EF will contain the same points. When ABCD is dilated the points EF will stay on the line segments AB and CD.
Step-by-step explanation:
When the figure, ABCD, is dilated, the points EF will remain on the figure. I just had this question a few minutes ago.
